Battery device and electric equipment

The utility model discloses a battery device and electric equipment. The battery device comprises a bar, the bar comprises a bar main body, a first connecting end and a second connecting end, the first connecting end and the second connecting end are connected to the bar main body, and at least one of the first connecting end and the second connecting end is electrically connected with a battery monomer; and the phase change structure is arranged on the surface of the bar piece main body, and the phase change structure avoids the first connecting end and the second connecting end. In addition, the chip is applied to the battery device for assembly, and the battery device is applied to electric equipment for power supply. By applying the technical scheme of the invention, the problems of high-temperature deformation, ignition and other risks of the insulating layer easily caused by over-high temperature of the chip can be solved.
